合成并表征了5，5-二（三甲基硅乙炔基）-2，2 '-联吡啶的平面铂配合物[Pt（Me 3SiC <$CbpyC <$CSiMe3）（C <$CC6H4Et-4）2]（1）。固态化合物1对CH_3CN和ClCH_2CN蒸气表现出独特的、选择性的、可逆的发光蒸发光致变色效应，可用于这些有害气体的检测。通过发射光谱和X射线衍射（XRD）图谱的动态变化来监测蒸发变色循环。X射线晶体学和密度泛函理论研究表明，1的汽致变色和汽致发光行为是由分子间Pt-Pt相互作用的变化引起的。
The planar platinum(II) complex [Pt(Me3SiC≡CbpyC≡CSiMe3)(C≡CC6H4Et-4)2] (1) with 5,5-bis(trimethylsilylethynyl)-2,2'-bipyridine was prepared and characterized. Solid-state 1 exhibits unusual, selective and reversible luminescence vapochromism to CH3CN and ClCH2CN vapors, which is useful for the detection of these hazardous vapors. A vapochromic cycle was monitored by dynamic variations in emission spectra and X-ray diffraction (XRD) patterns. Both X-ray crystallographic and density functional theory studies suggest that the vapochromic and vapoluminescent behavior of 1 are induced by the variation in the intermolecular Pt-Pt interactions.
